There are a number of Rare fish in Legion, and items (bait or otherwise) that will help you catch them.The Rare fish and items to catch them are zone specific (although some are obtainable on any shoreline of the Broken Isles).

Rare Fish

There are 18 rare fish coming in Legion that can be fished up. Each rare fish grants +5 to Fishing skill when used, consuming it in the process.

There are 3 Rare fish per zone, and 3 that can be caught on any coastal waters.

These can be fished up from a Fishing skill of 1, so this can be an effective way to power level Fishing.

If you are fishing with the Underlight Angler equipped, you will obtain a DIFFERENT version of each rare fish that grants Artifact Power instead of Fishing skill (e.g. you would fish up Coldriver Carp instead of Coldriver Carp)

Note that this does not retroactively apply to rare fish you obtained before getting the Artifact - the only use for these short of maxing fishing skill is vendoring for a decent chunk of change.

The Rare fish in the chart below are marked with a star (*)

Fishing Bait and Items

Some of the items that help you catch Rare fish will spawn and NPC that grants a fishing buff; others contain bait, or spawn NPCs that drop bait.

All baits are Unique, meaning you can only carry one. The further caveat to this is that you WILL NOT catch any bait that is currently in your inventory!

This can be used to your advantage if you are looking for a particular bait in a zone - by having certain baits in your bags, you will ensure you do not catch them again.

If you are wanting to obtain multiples of the same bait, you can put baits on the Auction House, mail them to an alt, or put them into a Guild Bank or Guild Bank Tab that only you have access to. This will allow you to catch the same bait again.

A portable mailbox like MOLL-E (Engineering) or GUMM-E (from the Draenor garrison Engineering Workshop) is a huge boon when doing this out in the field!

It is worthwhile saving some rare fish bait, in order to level Artifact Power on your Underlight Angler if and when you get it.

Found a pool (37, 22) by following @narya comment. It never disappeared like normal pools. Fished 21 Oodelfjisk from one pool. You need Ancient Vrykul Ring buff.

Comment by Gannon

Fished up 17 from a school located at 58.8, 59.7 right between Valdisdall and Skold-Ashil in Stormheim.

I just started trying out fishing in Legion and in less than 30 minutes, I managed to pick up the lure to see the Oodelfjisk schools and fished up enough of them to max out at 800 skill level. That is definitely the fastest I've ever leveled up fishing between expansions!

Comment by Graewolfe

Fished up the ring at Skold-ashil area several respawning stingray pools are around the shores. Little bit annoying with shark/fish agro and some undead around but consistent pools. Used the ring and there are a bunch of Oodelfjisk pools around as well so no need to run all the way up to cove of nashal. Oodelfjisk pools at 57.97, 62.36 and 57.52, 67.51, and 56.04, 69.80 and 59.69, 73.67 and 60.16, 74.42 There were more further down the river in both directions but didn't get to them before the timer ran out.

There is a school of Oodlefjisk at (46.61, 61.33) beside a fisherman that is stoned :)

Comment by Aeneias

I don't know if this counts as a bug exploit but today i discovered something :)When you are fishing for Oodlefjisk using Ancient Vrykul Ring , you have a chance to fish another Ancient Vrykul Ring..If you fish a second bait while already under the effect of that bait and if you use it adds to your total bait effect time.. Like if it's 2 minutes it becomes 4 minutes..BUT, if you use second bait when you have something like 45-55 seconds left, your bait time goes to 5 minutes.. And in that 5 minutes you have a high chance to fish another bait again.. Just reapply that bait again when you have 45-55 seconds left.At the end i fished 139! Oodlefjisk, 4 greybelly lobster and 5 thundering stormray. I fished baits of lobster and stormray under the effect of Ancient Vrykul Ring.. Took around 35 minutes at the same spot without moving. Around (38-60 Stromscar Gorge) Try it..

When you use this macro, it will consume any oodelfjisk you have in your inventory and cast the line in the same global because Fishing has no global cooldown. This allows you to make the most of each Ancient Vrykul Ring because you won't have to worry about inventory space as the artifact power granting rare fish do not stack like the ones fished without the fishing artifact. I also added in the Weather-Beaten Fishing Hat because I have it, you can adjust it as you need to based on what fishing modifiers you have.

Comment by OldWolf2

Oodelfijsken School also allows the catching of other rare bait -- so you can use the Ancient Vrykul Ring to summon pools for catching the other bait you need for Stormheim. I got a Soggy Drakescale.

Comment by Ollerich

With all the Ancient Vrykul Rings i got, the spot where the Oodelfjisk pool appeared, when using the ring, was always the same:

/way 53.5 67.5 Oodelfjisk Pool

Happy fishing

Comment by Magnognomus

I found one pool after using the ring at: 54.14 46.79

/way 54.14 46.79

It's hard enough to find the darn Ancient Vrykul Rings, then to have to search the area for the schools? Inside areas where hostile mobs are located, with a limited time to do it? What drugs were the programmers on when they thought of this crap? I know it can be done, I'm working on my second character for the achievement. But, damn, they could have thought this one out JUST a little better! Extend the timer, put in MORE SCHOOLS, don't HIDE the damn schools. What's wrong with having the damn school pop up close to where you fished up the ring? Why do we have to go searching for the school, with a damn limited timer? Two of the fish are 100% catch all the time IF you find the schools. What was wrong with the system in place for the other SIXTEEN rare fishes? Put the damn lure on, and hope rng gives you the fish in open water, or in the school! THINK Blizzard, think! Oh, and either fire the programmers on drugs, or share the damn drugs. One or the other!

Comment by Rtucci

Now I'm extra disappointed that I wasted the stupid ring in Suramar when I got it for a world quest reward thinking it was an actual ring. Why the hell is it a reward in Suramar anyways and why doesn't it give a confirmation or warning when using it?

Oodelfjisk pool at/way stormheim 38.27 20.40

Comment by SargonStarblade

Just in case anyone was wondering.

If you save up all the rare fish you collected while trying to get your Underlight Angler, like me, don't it won't work. The text is not changed once you get the Underlight Angler.

It still says:

Use: Toss the fish back into the water, increasing Fishing skill by 5, up to a max of 800.

Only new rare fish will say:

Use: Toss the fish back into the water, granting 50 Artifact Power to your fishing artifact.

finds school of fish that supposedly went extinct years ago

fishes them all up :P

Comment by RiokaR

After returning to the game and trying this, I was frustrated to realise I already had some of the lures in my bank, and as they are unique, I ended up wasting too much time fishing for nothing. This macro will check if you have an item hidden away in your bags or bank.
